Special ability: Big Bang
Long before Fire lord rise to power and before stormer and his rookie team there was Pyro juggernaut, the original fire lord he was ruthless, smarter and stonger than any of the past villians, his flame lit brigher and grew hotter than the sun, fire lord is but a mere candleflame compared to the fiery might of pyro juggernaut.
(Fire Fall)
Pyro juggernaut's capture was no easy task, eventually all the fuel depots were all dried up, he was runing low on fuel to keep active
if he were ever to be deactived a bomb he hidden in the HF base would detonate, from his Great flame sword and all the engine's around his body consuming/leaking fuel he needed refueling every so often, Also due to life support and being an older model
years later HF assembled new hero models who were immediately sent out to find and bring him to justice.
